97. Did God kill all the Egyptian cattle in the fifth plague?
Yes, they were all killed.
In the fifth plague of Egypt (the plague of cattle) "all the cattle of Egypt died."
Behold, the hand of the LORD is upon thy cattle which is in the field, upon the horses, upon
the asses, upon the camels,
upon the oxen, and upon the sheep: there shall be a very grievous murrain. ... And the
LORD did that thing on the morrow,
and all the cattle of Egypt died. Exodus 9:3-6
No he saved some to kill later.
More Egyptian cattle were killed in the seventh plague (hail).
Send therefore now, and gather thy cattle, and all that thou hast in the field; for upon every man and beast which shall be found in the field,
and shall not be brought home, the hail shall come down upon them, and they shall die.
And God killed "all the firstborn of cattle" in the tenth plague.
At midnight the LORD smote all the firstborn in the land of Egypt, from the firstborn of
Pharaoh that sat on his throne unto the firstborn of the
captive that was in the dungeon; and all the firstborn of cattle. Exodus 12:29
